Somewhere between training pots to actual display pots, lie these premium plastic pots. We use these pots to grow our potted material in the nursery, as do most Bonsai nurseries in the United States. As the thick plastic ensures they will stand up to the elements, without cracking or breaking for years. While remaining in good form, they are also a great depth and size to give your Bonsai room to grow, while getting used to the restrictions of a pot. 

If you're looking to train your Bonsai in a premium pot, without the premium price tag. Try one of these Taiwanese Pots.

Although both types have sufficient drainage for Bonsai, we prefer to use the oval-shaped pots, as they have superior drainage. 

 

Size:

Rectangle - 9.5" length x 7" width x 3.75" height

Oval - 9.5" length x 7.5" width x 3.25" height

Soil (Substrate)

Bonsai soils are usually a mixture of organic potting compost (Pine Bark or Forest Floor), Akadamapumice, lava rock in varying amounts. 

It is important for the soil have good water retention while also draining well, along with very good aeration. The quality of the soil directly affects the health, size and growth of your tree. One of the worst things you can do to your tree is plant it in regular garden soil. Garden soil hardens when it drys and can often lead to a disadvantage when growing a Bonsai. 

Soil mixtures can be purchased here, but given their weight and cost of shipping, you can also easily make your own. 

 

Depending on the type of Bonsai you're growing, here are the general formulas for successful mixtures. 

Deciduous Tree (Leafy and looses leafs in the fall)

50% Akadama

20% Pumice

20% Lava Rock

10% Potting Compost

 

Coniferous Tree (Evergreen like Juniper, Cedar)

1/3 Akadama

1/3 Pumice

1/3 Lava Rock

 

If you are not able to check on your Bonsai's moisture levels daily, add more Akadama to the mix. 

Given how these soils erode over time, repotting every 2-3 years is required. 

 

Here are some suitable replacements if you cannot find the recommended types of soil.

  • Akadama - fine fired or baked clays, some even recommend cat litter as a substitute. 
  • Pumice - fine crushed aggregates, expanded shale and vermiculite.
  • Lava Rock - This can be replaced with fine gravel or you can also look into purchasing a larger lava rock at a hardware or gardening centre and crushing it. 

 

Fertilizer

One of the best and easiest ways to fertilize your Bonsai, is to add a liquid fertilizer mix when water your Bonsai's once a month during the spring/summer. If your Bonsai looses leaves in the winter there is no need to fertilize it then. If you have a coniferous tree, fertilizing the tree once in the beginning of winter and once in the middle of winter should be sufficient.
